Vibration in my left ear?

You just cleaned your ears? Did you know your not supposed to stick anything inside your ears bigger than your elbow? The only reason earphones are ok is because they are specially shaped & won't damage but cottonbuds & other things can seriously injure your ears!! I used to clean my ears with cotton buds and I kept getting infections. When I stopped cleaning, I stopped getting the infections. You probably have self inflicted (with the loud music & ear cleaning) a temporary tinitus. There's nothing you can do to stop it. Just be glad it's not permanent as many musicians have it 24/7!
